Page Created : OPENEJB : Remote Server Remote Server has been created by David Blevins (Sep 02, 2005). Content: Accessing EJBs Remotely When using OpenEJB as a stand-alone server you can connect across a network and access EJBs from a remote client. The client code for accessing an EJB's Remote Interface is the same, however to actually connect across a network to the server, you need to specify different JNDI parameters. Short version Using OpenEJB's default remote server implementation is pretty straight forward. You simply need to: Deploy your bean. Start the server on the IP and Port you want, 25.14.3.92 and 4201 for example. Use that information in your client to create an initial context Add the right jars to your client's classpath So, here it is in short. Deploy your bean with the Deploy Tool: c:\openejb> openejb.bat deploy beans\myBean.jar See the Deploy Tool documentation for more details on deploying beans. Start the server: c:\openejb> openejb.bat start -h 25.14.3.92 -p 4201 See the Remote Server command-line guide for more details on starting the Remote Server. Create an initial context in your client as such: Properties p = new Properties(); p.put("java.naming.factory.initial", "org.openejb.client.RemoteInitialContextFactory"); p.put("java.naming.provider.url", "25.14.3.92:4201"); p.put("java.naming.security.principal", "myuser"); p.put("java.naming.security.credentials", "mypass"); InitialContext ctx = new InitialContext(p); If you don't have any EJBs or clients to run, try the ubiquitous Hello World example. In OpenEJB 0.9.2 and before, add the following libraries to your clients classpath: openejb-x.x.x.jar openejb_client-x.x.x.jar In OpenEJB 1.0 beta 1, add the following libraries to your clients classpath: openejb-core-10-beta1.jar Both can be found in the lib directory where you installed OpenEJB.
